The maximum size limitation shall apply to each side of a sign or sign structure. A maximum of 2 signs may be erected in a facing, in which event the facing shall be deemed to be one sign, the size of which may not exceed the dimensions listed in this Section. Signs may be double faced or be placed back to back or V-type or triangular, provided that the angle between sign faces shall not exceed 90 degrees. The area shall be measured by the smallest square, rectangle, triangle, circle or combination thereof which will encompass the entire sign.
